Tuvok once suggested sundaes as an alternative answer to the following riddle: "A lone ensign finds himself stranded on a class L planetoid with no rations. His only possession, a calendar. When Starfleet finds him twelve months later, he's in perfect health. Why didn't he starve to death?" According to Tuvok, he might have eaten the sundaes (Sundays). (VOY: "Riddles")
